Haig–Simons income
Haig–Simons income, Schanz–Haig–Simons income, or Haig-Simons-Hicks income is an income measure used by public finance economists which defines household income as consumption spending plus change in net worth. It is represented by the accounting identity: Haig-Simons Income = Household consumption spending + Change in household-sector wealth (ΔNet Worth) The biggest difference between Haig-Simons income and more widely-employed Household or Personal income is the inclusion of accrued household holding or "capital" gains in the Haig-Simons measure.
